CURRENT RETARDER.

Application filed April 6, 1925. Serial No. 21,144.

This invention contemplates the provision of what Iterln :1 current retarder, adapted to be arranged adjacent the bank or the like to prevent strong current-s from cutting a Way the land, by changing the course of the current in a direction away therefrom, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a top plan view of the invention.

Figure 2 is a rear elevation.

Figure 8 is a sectional view on line 33 of Figure 1.

Figure 4; is a sectional View on line l 4; of Figure 2.

Figure 5 is a perspective view of one of the weights.

The invention embodies a frame which may vary in shape and size without departing from the spirit of the invention, but

which frame is preferably of the outline illustrated in Figure 1. In this connection it will be noted that the frame includes a back port on and an end portion, the latter being disposed obliquely with relation to the back portion as shown. Each of these portions includes spaced upper and lower parallel members and 11 respectively which are suitably braced by connecting strips 12, while the back portion and end portion are further connected and strengthened by diagonally arranged braces 18. The frame is arranged vertically adjacent the bank of a stream or the like, and supports a wall designed to change the course of the water away from said bank, to prevent strong currents of water from cutting away the land as will be readily understood. This wall may be of any suitable construction and design, but preferably consists of two obliquely disposed sections illustrated in Figure 1 to direct the water away from the land as indicated by the arrows in said figure. Thewall preferably embodies an auxiliary frame including obliquely. disposed sections 14 and 15 respectively, which are supported by the respective portions of the frame hereinabove described, the two frames being connected by suitable bracing and supporting elements 16. The longer section of the wall is terminally connected with one end of the main frame, while the short obliquely disposed section 15 of the wall connected with the end portion of the main frame as clearly shown in Figure 1. This wall preferably includes boards or planks 17 which are secured to the auxiliary frame 14. Carried by the main supporting frame and suitably located is a plurality of weighted elements 18 each of which is provided with an eye 19 adapted to be associated with said supporting frame, With the width-projecting beneath the lower edge of the frame and adapted to be embedded in the ground or surface to hold the entire structure fixed with relation to the ground in its given position. The frame of course is partly sunk within the ground to afford it the proper strength and rigidity for the purpose for which it is intended. It is manifest from an inspection of Figure 1 that strong water currents flowing in the direction of the bank, and especially in the direction of a protruding portion of the bank, can be deflected and its course changed in a direction away from the bank, to prevent the Water from cutting away the land. It is of course to be understood that the structure can vary in size, and be made in proportion to the size and advance of the water of the stream.

While it is believed that from the foregoing description, the nature and advantages of the invent-ion will be readily apparent, I desire to have it understood that I do not limit myself to What is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim:

A current retarder comprisin a frame adapted to be arranged vertically against the bank of a stream, and including front and rear sections arranged substantially V- shaped in plan, said frame including an additional section projecting forwardly from one end thereof and suitably braced, a Wall to the first mentioned Wall, and against which the Water is directed from said first mentioned section, and caused to move away from the bank, and means carried by the frame and adapted to be embedded in the ground for supporting the frame in position 10 for use.

In testimony whereof I afiix my signature.
